以断奶大鼠为模型,观察了富锌酵母的生物利用率,并与无机锌制剂进行比较。结果表明,12ppm富锌酵母组的动物增重最多,饲料消耗量大,饲料效价最高,能有效地纠正锌缺乏状态。在同样剂量条件下,富锌酵母的毒性作用较无机锌为低。以富锌酵母作为食品添加剂,是补充锌的良好来源。 Weaned rats were used as models to observe the bioavailability of zinc-rich yeast and compared with inorganic zinc preparations. The results showed that animals in the 12ppm zinc-enriched yeast group had the highest weight gain, large feed consumption, and highest feed efficiency, which could effectively correct zinc deficiency. Under the same dose conditions, the zinc-enriched yeast was less toxic than inorganic zinc. Using zinc-rich yeast as a food additive is a good source of supplemental zinc.
